To a 1.1"]! on: if m (11 oncern:

lie it known that we. VAL'll-IR M. Scuwanrz and lTAltltY (.UILS'IUN; citizens of the United States. and residents of Philadelphia. lcmisvlvania. have invented certain Improvements in Machines for Drying llosiery of which the following is a specification.

The object of our invention is to coi'istruct a machine for thoroughly and quickly drying hosiery.

The machine consists essentially of a drying chamber; a series of forms on which stockings to he dried are placed; and means for conveying the forms so as to cause them to travel into and through the drying chamber andont again; the rate of travel of the forms being such that the operator has time to place a dampened stocking on each form, as it passes. and to remove-a dried stocking; the operation of the machine allowing for the rapid and siurcessful accomplishment of the work for which it is intended.

In the drawings we have illustrated a machine having four tables and four independent driers. so that four operators place the stockings on the forms; two operators removing the stockings from the forms.

It will he understood that while we have illustrated a machine of this type, a machine ha viug a single drying chamber and a single table may he used without departing from the essential features of the invention.

In the accompanying drawings :Fi'gurc' 1. is a perspective view of our improved hosiery drier; illustrating our invention; Fig. 2, is a vertical sectional view on the line 2-2. Fig. 1; illustrating the drying chambers and the means for circulating the heated air through the chambers; Fig. 3, is a plan view; Fig. 4, is :1V plan view of one section of the drier showing the forms in position and the drier casing removed; Fig. 5, is a plan view showing the cams for feeding the carriers, on which the stocking forms are mounted, over the' table and through the drying chamber; Fig. 6, is a transverse sectional view on the line 6-43, Fig, 4; Fig. 7,

is an enlarged sectional view on thegline 7T7, Fig.

of one of hstocking forms; Fig. 8, is a side vie\ oFthe-carr'er illustrated in Fig. 6; Fig. 9 a sectional plan view 0 the line '-99,Fig. .8; Fig.10, is an inverted pla'n section there is a steam coil 4 showing a carrier and a portion.

view of the carrier illustrated in Fig. 7; and Fig. 11.'is a plan view of a modification of the table and drying chamber.

Referring to the drawings. 1 is the base of the machine mounted. in the present instance. on legs 2. This base is shaped, as clearly shown in Fig. 3. and has four tables, two on each side of the machine; the tables on each side being spaced apart forming recesses 5 for the ope ators who remove the stockings from the stocking forms.

Projecting upwardly from the base is a drying chamber (3, made as clearly shown in Fig. 1 having four compartments 7, one for each table t. The face of each compartment is inclined as shown, and the central portion is vertical so as to increase the space for the operators above mentioned. In the central portion 8 of the drying chamber 6 is a vertical partition 9 which divides the drying chamber into two sections, and in each 10 for heating the air which is circulated through the drying compartments.

.11 is a horizontal shaft having bearings 12 mounted in the frame of the machine and driven from the main driving mechanism. ()n this shaft 11 are fans 13 which are located in openings in the vertical'partitions It so that the air circulates past the steam coils and through each section of the drying chamber; thoroughly drying the stockings which pass therethrough. i

The drying chamber is made of a frame open on all sides and in order to close the frame there are end plates 15 held to the frame by suitable clamps and side plates 16 also held by clamps and having slots 17 therein for the pas age of the stockin forms into and out the machine. The eating section of the drying chamber is closed by plates 18, as clearly shown in Fig. 1. This construction may be-modified, however, and some of the plates may be permanently fas tened in position, but weprefer to make them detachable so that in case of needed repairs, access may be readily had to the interior of the heating chamber. On each side of the slots 18 are mounted guides 19 for directing thestocking forms into the slots. By providing narrow slots, very little heated air escapes from the heating chamber.

In the base of each table 4 are four shafts ings 24, Fig. 5. On the shaft 20 is a gear 7 wheel 25, which meshes with a gear on the driven shaft 26. beveled gear wheels 27, which mesh with beveled gear wheels 28 on the shafts 21 and 23 and on the opposite end of each of these shafts is a beveled wheel 29 which, in turn, meshes with tr'bevel wheel-30 on the shaft 22, so that all of the shafts turn in unison.

Secured to the shaft are brackets 31 to which is-secured the scroll cam 32 in the form of a ribbon. This cam acts to feed the carriers for the stocking forms forward 38, which passes the projection 3 across the front of the table and while the forms are being traversed by this cam, the

operator; (or operators) :places the stockings on the different stocking forms.

33 is a scroll cam secured to the shaft 21 and made in the samemanner as the cam 2-32. This cam feeds the carrier into the drying chamber. 34 is' a scroll cam on the shaft 22, which feeds the ca'rriersacross the drying chamber and 35 is a scroll cam on the shaft 23 for feeding the carriers out of the drying chamber. and into position for the operator to remove the dried stockings from the stocking forms.

It will be noticed that both the cams 33 and 35 stop some distance from the cam 34 at the delivery end of the cam 34.

to dwell for a given length of time in the drying chamber'so thatwhile there ispractic'ally a continuous movement of all of the carriers, a certain number of carriers remain stationary for a predetermined length of time within the drying chamber, consequent-1y, there are more carriers and stock:- in'g forms'within the chamberat all times than there are outside; giving ample time for the stockingsto. become thoroughly dried, yct allowing for the continuous movementof the carriers-while one stocking is being'removed fromlthe form and anof her placed thereon. s

The ends of the cams which are located a right angles toeach other "are so formed. that as one cam delivers a carrier to a certain point another'cam removes the carrier laterally from the position; one cam, however, holding the'carrien until the other camhas properly e gaged it so that the car-- riers areat. all times. under the control of the cams. j I

In the present insta'hce,'the delivery end of each cam has a reduced projection 37 at right angles-t0 the center line of the cam,

while at the opposite end-is a tapercdhpollnt att e elivery end of each cam so that the carriers are traversed and fed in a direction at right angles to their revious movement.

-39"39, 'areit e carriers made as clearly Also on the'sliaft 20 are 'l he base 40ot each carrier travels in guidethe present instance, by screws 51. This shown in Figs. 6 to lOinelusive. Each carrier has a base 40 from which projects a stud 41 having a roller 42 which is engaged by the several cams 32 to 36 respectively.

ways 43, 44, 45 and 46 in the table 4, as clearly shown in Fig. 4-and, as before remarked, the cam 32 traverses the carriers across the front of the table. The cam 33 feeds the carriers longitudinally into the drying chamber; allowing them. to accumulate, as illustrated in Fig. 4, and as one carrier pushes another forward the cam 34 engages a carrier and moves it laterally in the slot 45 across the drying chamber; the 30 cam 36 engaging the carriers and moving them longitudinally toward the outlet opening; the carriers accumulating in the slot 46 and as one carrier pushes another one forward it is engaged by the cam 35 and moved out of the heating chamber and into the path of the cam 32.

While the carriers are traversing the slats. outside of the drying chamber, as'before remarked, there is su-flicient time for one stocking to be removed from the stocking forms and another placed thereon; the drying process being repeated over and over again. Q a v On each carrier39 is an inclined projecting bracket 47, Figs. 7 and 8, and plvotally mounted on this-bracket is'a cylindrical block 48 having a projecting rib 49 to which the stocking form or board 50 is secured, in I stocking formis g ven an inclined'positio'n, as clearly illustrated in Figs. 1, 4,-and 8, which allows the operator to more readily place a stocking on its form, prior to being traversed through the heatingchamber.

By swiveling the stocking form on the carrier,.-the forIn-canbepresented sidewise to the operator, who places the stocking on the form, as it-has been found-that a stock-I ing can be more readil and accuratel I placed on a form, when't e form is in ,tlnsslanting position; all portions of .the stocking being properly stretched-over theform. On the rotating block 48 are two wings 52 and 53 and on the" under side 'of thecair 5 rier is a slotted projection 5.4.-- After the stockings are dried and before they are forced out of the slot 17 -in the casing, the forms must be turnedso as to. be presented to the slot on edge and this is accomplished 120 .by .a disk 55 located within the drier in a position tofcont-act wit h the lowerportion of the stocking form 50; causing the stocking form to turn at right'angles-and thusallowingit to pass, through the narrow slot 125 17 in the casing. In or er to present the Y stocking form 'sidewise gtothe operator, we secure a lug 56; on the fixed guide of -the'.=,."

table which contacts with the w'ing'; 53 6f. ca rz 'ie r moves. 130

the block 48 a'ndas' each will be node this lug, the lug turns the -dit l' erent slocking forms at right angles, as illustratedin Fig. 4. 'There is no change in the position of the form as the carrier travels across the 6 table until it reaches a point in front of the' other slot 17 of the casing, when it again turned at right angles .by the slotted lug 54 'on the under side of the block 48 engaging the beveled end of the guide 57; which turns the stocking form so that.- it will be presented toe forward to the slot '17 and after it passes through the slot and 18 within the drying chamber it is again turned at right angles by a projection 58,which is engaged bythe wing 52 on the block 48;-remaining in this position until it is again turned at right angles by the wheel 55, as described above...

- By this arrangement not only are .the forms so .turnedthat they-can pass through a very narrow slot in a casing of the heating cham-\ her, but theyare presented in the best position to the operator to place a stocking thereon and the forms aresoarrang ed in the dryingchamber that ,a number of them can be located side-by side, (while in the chamber) allowing a large number of stockings to re= maiii'iwthe'dryin'g chamber thus facilitating the process of drying. In order to limit the movement of the.

In thepresentinstance, the shaft 11 is the-driving shaft having a pulley 60 for the to power belt and on theopposite cnd"'of.. the shaft is a pulley 61 around which passes a belt .6210 a pulley 63 on a sliaft-tstfmount ed in suitable hearings 65 and, in the present '-.instance,- there .is a-reducing' gear in the 45' gearbox 66 which is betweenthe shaft 64' I and the pulley 63,1butthis construction may be' dispensed with in some instances. without "departing" from .theessential features of the -invention." v p i l On t-heshaft 64. int-he present instant-c. 'are chain. wheels 67 and chains 68 pass around these chaiii wlieels and aronndrhain -w. heels 69 on shafts located within a change gear box 70. Theshaft on which thlr chain wheels.69,are mounted is gearedto the shaft 26- ca-rrying the gear wheel, 1 which mesheswiththe gear wheel 25 on the cam shaft 20 .above described.

.A machine of the al'iove described type. consists suhsta tially of four units. but it. odd -t,hati'a single unit. ma? caine may be"employe'd; said-singl' unitma n fljaving bntpne table or a two unit' '11}! inep havingftfiwo -tables-iimay be used, ting. -o qn e' ha ving more than four operator to perform the work. i

on each side thereof and line conveyerst'ravel [operator to adjust the, stockings ontothef tables may be constructed, without departing from the spirit. of the invention.

Thus it will be seen that we provide a series of movable carriers .on which the stocking forms are mounted; means being also provided whereby they are brought in front of an operator so that a stocking may be properly placed upon a form. Then the stocking has been properly placed-in the desired 1xisitioii,tlie form is turned and allowed to pass through a narrow slot in the drying chamber; the forms collect-ing'and remaining in the drying chamber a sutlicient length of time to allow the dampened sto kings to be thoroughly dried. The forms are then turned and forced out another narrow slot in the drying chamber and brought in position for the operator to remove the dried stocking.

We preferably speed the machine so that only two operators are required; one operator placing stockings on the stocking forms and another; removing the dried stockings from the forms, but it will be understood a i that in some instances the machines may be driven at such a speed as to allow one \Vhile our invention is intended primarily for a stocking drying machine; a singeing device mayfbe used in connection with the drier to singe stockings while they are on the. forms and the. fecding mechanism for thecarriers and stocking forms may be used in connection with amachine for singeing,

where the sin'geing is a separate operation;

"In Fig. 11, we have illustrateda modifica' tion of our improved drier, in which there is a central drying chamber 6" longitudinallyarranged. An operators table 4.-is"l0cated' m a. (midi-angular, guidevyay; traveling across the table and allowing time for .the'
